Honda TRX450R Specs and Review 2022

Honda TRX450R: An authentic representation of racing The Honda TRX450R‘s sturdy design and unbeatable power milling capabilities allowed it to be atop podiums all over the globe.

Many expected the Baja winner to have sharper plastics, more aggressive designs, and a motor that was fuel-injected further down the road. 

Honda TRX450R

Roll cages were the first machines to take over the race ATV scene. It wasn’t until the recent increase of two-strokes that off-roaders began to consider this racer of 450 classes.

The Honda TRX450R (a.k.a. Honda SporTrax 450R) is a quad that won championships and was released on the market between 2004 and 2014. 

It has a 2 stroke engine of 449 cubic centimeters a top speed of 74-mph and a race-inspired chassis, this 4×4 made its mark in the history books by winning four times in the tough Baja 1000.

While it was highly praised on track, However, it was not a race car. Honda TRX 450R did not make its debut on the ATV scene with guns in the air.

It wasn’t until its final calendar year when the TRX450R placed 2nd of the 30 sport ATVs, and also released the most powerful, exclusive trims. 

Despite its waning display of power, it has always been praised for its racing capability.

The Baja-Winning Honda

The Baja-Winning Honda

For the entire duration of its manufacture, it has been a top-quality machine. Honda TRX450R has been a proven winner on both circuits for racing off-road and motocross. 

It is refined, powerful, and flexible, the 450-class machine provided excellent control on tracks, and also in sandy dunes or trails.

From the beginning, it was built to be a Baja-winning tradition With a simple design that is designed for top-quality riding and the capability to leave the pits in a hurry.

Though it was rumored that it would take its power unit from CRF450X and CRF450R, which are both award-winning Honda engines, the TRX450R first disappointed a few enthusiasts who believed that the quad’s engine was weak. 

Fortunately, this didn’t hinder most people from acquiring the trusted, reliable machine.

In the years following its beginning, Honda finally introduced changes to the four-wheeler (detailed in a subsequent part of the article) that made it more similar to the Honda 450R.


Contrary to how current 4x4s are constructed and designed, the Honda TRX450R model is not appropriate for a beginner. 

Its features like its Unicam(r) valvetrain, the Keihin FCR carburetor and championship-geared suspension, and many other components in addition to its extreme nature – are best with the skill of an experienced rider.

It’s not surprising that this four-wheeler is widely regarded as the weapon of the pro-off-roader of choice. It is true that the TRX450R was the first factory-sponsored quad ridden by Tim Farr to compete in the ATVA MX, TT Nationals in the Pro-Production class as well as the 2004 Baja 1000 nationals.

Honda TRX450R Specs (2004 Honda TRX 450R vs. 2009 Model) Engine and Lubrication

Despite the initial belief that the SporTrax 450R was derived directly from (Honda the 450R) CRF450R dirtbike’s power source, the only thing they are able to share is their displacement.

It was not until the year 2006 it was not until 2006 that Honda revamped the TRX the 450R to improve its mechanical components to its motorcycle counterpart. 

The result was an increase in power output, from 33 horsepower to 41 horsepower.

Of course, changing the jetting of the 4×4 beyond 1500m (4,500 feet) is not a must because the high altitude can result in an abundant mixture that can adversely impact engine performance, and power delivery, and cause an increase in the consumption of fuel, or cause drivability issues.

The TRX450R is equipped with a five-speed manual transmission as well as an automatic clutch system that is controlled by an O-ring chain 520.

This combination of powertrains, paired with a lower rider’s position, a more efficient exhaust system, and brand new porting of the cylinder head, is made with the lightweight Nikasil lining that makes the TRX450R race-ready and trail-friendly.

Furthermore, the CRF-style handlebar grips, as well as a clutch and front brake lever, contribute the four-wheeler a superb handle and mobility.

The first model of the SporTrax initially came with distinct kick-start and electric-start trims. These were later combined for the 2007 Honda TRX450R, up until more recent models.

The format of the battery required to run the four-wheeler is a one-year YTZ7S (view the format on Amazon) format that is typically extremely high-performance and maintenance-free. When you need to service the battery, you’ll find the battery inside an area under the right rear of the fender.

The overall dimensions of the Honda TRX450R slightly increased, but the width and capacity for weight were not changed. 

The almost negligible increase in size is quite impressive considering the overhaul of the engine as well as the protection equipment fitted to the SporTrax starting in the year 2006.

It is the Honda TRX 450R is generality unbreakable – thanks to its sharp design and sturdy components.

If there’s a single area that needs improvement the area is instrumentation. It comes with the standard brake, clutch, and engine controls as well as switches. 

However it is the SporTrax doesn’t have an odometer, speedometer, as well as an even an oil temperature sensor.

If you’d like to take note of your miles or hours as well as speed rating, you’ll have to buy a trail Tech 752-121 Black Vapor Digital Speedometer Gauge Kit (view on Amazon) as an additional accessory that is worthwhile!

Improvements Post-2006Improvements Post-2006

Improvements made for modifications made to Honda TRX450R can be divided into two separate episodes. 

The first round of enhancements focused on the car’s mechanical components, engine as well as power output.

However, the second round of improvements was more cosmetic in terms of design. This is a brief overview of the changes that the Honda TRX450R experienced during its 11-year run of production:


  • There was a 96mm bore increase, and the stroke decreased by 62 millimeters.
  • Models with kick start and electric power were added.
  • The compression of the engine went from 10.5:1 to 12:1 with the second generation engine.
  • The SporTrax(r) came with an active cam profile as well a brand-new shorter skirt (forged slipper) piston, as well as titanium valves.
  • Honda modified the carburetor from the round-slide Keihin 42-mm type to a flat-slide FCR model.
  • The ratios of transmissions have been reduced and designed to be more suitable for trail and racing use.
  • The maximum engine RPM was increased from 9,800 to 9,850 however, some sources online indicate a redline RPM of 10,500 in stock and power of just 38 horsepower (28.34 kW) rather than the advertised number of 41 horsepower.
  • A longer swingarm, as well as a new linkage arrangement, helped ease the problem of bucking that was present in earlier models.
  • A reduction of 8mm in the rider’s position has resulted in an improvement in center-of-gravity as well as handling.
  • The rear suspension travel was increased by 9 inches (230 millimeters) up to 9.3 inches (240 millimeters).

2007 until 2007 to

  • The appearance and the repositioning that comes with the automatic decompression feature as well as the addition of the electric start-up in certain trims offer excellent hot-starting as well as cold-starting.
  • Honda has introduced the new White and Black/Flame color options on the models with an electric start on the 2007 TRX450R.
  • The brand new White that comes with an Orange frame color is available for 2009 TRX450ER models.
  • New body panels in Black and Blue join White ones on trims with electric start.
  • Black rims were a popular choice with white and orange frame plastics.
  • Reflectors were upgraded to provide better visibility and an attractive appearance.
  • Retro-inspired Retro-inspired Special Edition trims were released within the last 2 years on the Honda TRX450R.
  • HRC Power-Up Kit, as well as ATV trailerable cover, were offered through dealers at the time of purchase.

Although a fuel-injected version of the model for the 2018 Honda TRX450R had been rumored to be released from 2009 onwards The trim did not make it into production. 

The last model released under the SporTrax range is the 2013 Honda TRX450R. 

It was equipped with all the above engine and aesthetic enhancements, however, many Honda fans were hoping for a more user-friendly quicker, more efficient, and stable version.

Honda TRX450R Price

Prices listed found on Craigslist as well as other auction websites range from $1,400 to $9,500 with 2005 TRX450R models carrying the most expensive price. 

The majority of these models are within Oregon, California, and other states in the region.

In most cases, four-wheelers that are in good condition will cost a minimum of $5,000, and anything less is offered as complete units, with minor cosmetic issues or some work that is top-of-the-line.

In terms of the lineup’s original MSRP I decided to go ahead and combined the information into the following table (Note that there aren’t listed prices available for the models ’10 or ’11, and the list prices for Special-Edition trims are assumed to be the same):
